The elastic expansion structure can be adjusted by screwing the upper nut, thereby extruding the top fixing sheet, so that the elastic expansion sheet is extruded, the elastic expansion sheet is opened (according to the extrusion degree, the opening degree of the elastic expansion sheet is also different, so that the adjustment is realized), and the bottom fixing seat can also be adjusted by the same method, thereby extruding the elastic expansion sheet.
[0006] The bottom fixing seat comprises an elastic expansion sheet limiting block, the elastic expansion sheet limiting block comprises a plurality of limiting grooves, and the limiting grooves and the elastic expansion sheets are arranged in one-to-one correspondence. The limiting grooves can limit the elastic expansion sheets, and can also avoid the inward deformation of the elastic expansion sheets.
[0007] One end of the screw rod is provided with a base table, and a plurality of steps are arranged on the base table. The plurality of steps are also used to limit the bottom of the yarn cylinder to a certain extent.
[0008] The other end of the screw rod is provided with a nut. The nut is arranged to limit the elastic expansion structure at the screw rod.
[0009] This utility model discloses a yarn bobbin fixing mechanism for an air converter. The mounting base is provided with several yarn bobbin fixing components, and the nut and the bottom fixing base are threadedly connected to the screw. The elastic telescopic mechanism is not threadedly connected to the screw. Therefore, in practice, the elastic telescopic mechanism can be compressed by adjusting the nut and the bottom fixing base, thereby obtaining a support structure suitable for yarn bobbins of different diameters. Since there are several elastic telescopic mechanisms, various parts of the yarn bobbin can be supported. Attached Figure Description
